Key Specifications Parameter Category Specification Product Type Zone Control Unit (Safety & Cabinet Control Module) ABB Model ZCU-14 Order Code 3AXD50000005164 Primary Application ACS880 multidrive and other large ABB cabinet drive systems. Key Functions • Safety Interface: Processes safety inputs (e.g., emergency stop, safety door monitors) and controls safety outputs. • Cabinet Cooling Control: Controls and monitors cabinet ventilation fans, including fault detection. • Auxiliary Power Supervision: Monitors voltages of auxiliary power supplies within the zone. • Interlocking Logic: Provides programmable logic for interlocking between drives and external processes. • Diagnostics & Communication: Features LED status indicators and communication interfaces (typically via the drive's main control system). Typical Inputs/Outputs • Digital Inputs: For safety devices, temperature sensors, fan status. • Digital/Relay Outputs: For controlling contactors, fans, and status signals. • Communication: Integrates with the drive system's higher-level controller (e.g., via fiber optic or bus system). Mounting Designed for mounting inside an ACS880 or similar multidrive cabinet. Safety Role A key component in implementing the drive system's overall safety functions (e.g., Safe Torque Off - STO coordination, cabinet access safety).
